FRElGHT-CAR-DOOR LOCK.

SPECIFICATION formingpart of Letters Patent No. 276,283,.dated April 24, 1883.

Application filed December 21, 1882.

To all whom tt may concern:

Be it known that I, HORATIO G. H.REED, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Locks for Freight-Gar Doors; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to the lockin g of freightcar doors, and will be fully described herein after..

In the'drawings, Figure 1 is a plan view of a portion of the side walls of a freight-car, and Fig. 2 is an inside view of the same.

A is a side and B is an end door of the car. a is an elbow-lug, secured near its upper edge to the side door, and Gis a bifurcated dog, that is pivoted to the inside of the car, so that its arms 0 0 will project down in position to engage with the lug a when the door A is moved back and forth.

The arm 0 of the dog Oterminates in apivoted finger, 0 while the arm a is connected. by

.a rod, D, with one end of a spring-bar, D, the

. is the case the pin d is held in the door B by the pressure of the lug or upon the arm 0 of (No model.)

of the bar D, which bends as the lug a presses the bar D toward its end of the car. When the door A is opened the lug a, striking the finger c and crowding under and past it, will turn the dog 0, so as to cause its arm 0 to draw upon the rod D and spring-bar D, thereby withdrawing the pin d from the perforation in the door B; but as the door A is again shut the finger a will yield and permit the lug a to pass beyond it to the arm 0. I proposein this way to connect each side door with an end door, and thereby do away with any necessity for climbing over the freight in a car to lock or unlock the end doors.

With my device, as soon as the side doors are opened, the enddoors become unlocked, and the closing of the side doors locks the end doors, if they are closed; but if they should be open when the side doors are closed it is only necessary to close them and the pin 01 will fly into place.

Having thus-described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The side door of the car, having a lug, a, in combination with a dog, O, the pin d, and connections, as set forth.

2. The combination, with an end and side door of a car, of the spring bar and its pin, bar D, and dog 0 and lug a, as set forth.

3. The dog 0, having arms 0 c and finger 0 in combination with doorsAand B, pin d, and connections D D, as set forth.

In testimony that l'claim the foregoing I have hereunto set my hand, on this tt-h day of December, 1882, in the presence of two witnesses.
